Some filters won't work with wrapper scripts

I guess this could be an enhancement and make things easier for people using tools like nodenv to manage nodejs versions.

I've found this issue while using the Uglifyjs filter but the CoffeeScript filter does the exact same thing.

These filters call nodejs passing a file from /usr/local/bin. We're guessing the file in the bin directory isn't executable by itself (while it should) and that it will be the Javascript file, not some wrapper around it. In my case, I have links to the nodenv shims and thus the filter fails.

I think the best fix would be changing the configuration seetings so that I could just point to an executable without caring about nodejs versions and paths when I don't need it.

I could accomplish this using this config:

'node' => '/usr/local/bin/uglifyjs'
'uglify' => ''

But this could read easier as:

'uglify' => /usr/local/bin/uglifyjs'

And make it the default configuration since it should work in most cases I guess. The node and node_path settings should be seldom needed.

I'm open to changing it as long as we don't break the use case of having a node_modules in an application. We may not need the NODE_PATH environment variable as npm has improved bin stub generation in the time between these filters being created and today.
